patote succesfully installed the resulting 3.55 PUP on a Retail console. The console is in locked mode after installation of the firmware. 

 patote	8294 does nothing
 patote	0168 does nothing
 patote	5138 does nothing
 patote	1739 worked fine
 patote	or not ; it didnt said wrong password ; but all is still locked
 patote	2297 nothing
 patote	the code is................. 0000
 patote	and now the install package files and app_home are back in game menu
 patote	ohhh ; and in system too ; all the way down
 patote	if you go to security settings and do l1+r1+select+square it goes back to demo without turn the unit off
 patote	thats system settings install packages option only does blind installations
 patote	you cant browse the thumbdrive ; it just starts installing all the pkgs in the drive
 patote	it works ; but fails in geohot signed ones ; the regular ones installs without problems
 patote	theres another extra option
 patote	automatic update
 patote	"sets wheter to update the system software automatically via internet when the ps3 system is turned on"



FSELF patch appldr

MFW does not seem to have (proper) support for fself's. 

Mathieulh	why do all those emu devs actually use geohot's tool on their selfs, I wonder xD
Mathieulh	the proper format to use is fself
Mathieulh	there are existing patches for fself on 3.41
Mathieulh	but those guys who make those so called cfw didn't port many patches at all
Mathieulh	if not any
Mathieulh	and the memory patcher one for fself isn't there
eussNL	ehm, including MFW Mathieulh ?
Mathieulh	you should just patch appldr
Mathieulh	and make the function that detects the model return true for debug
Mathieulh	and you get native fself + edata
Mathieulh	it's an easy patch
Mathieulh	you can also patch the sign check along with it
Mathieulh	4 bytes to patch
eussNL	I dont see a mention of appldr patch in MFW or I am overlooking it
Mathieulh	yeah MFW doesn't do that
Mathieulh	but there is a lv2 patch for fself too
Mathieulh	(memory patcher)
Mathieulh	at least in 3.41 there is
Mathieulh	it's in psgroove
Mathieulh	but it doesn't work for compressed fself
Mathieulh	it's better to patch appldr
Mathieulh	besides I use compressed fself on all my shit now xD
Mathieulh	saves some room :P
Mathieulh	people should just use fself anyway
Mathieulh	that way you don't need to sign or encrypt
Mathieulh	and it's future proof
Mathieulh	the geohot signed shit doesn't work with 3.56+ cause of the whitelistù
Mathieulh	so you have to patch the whitelist check in the ldr to get them to run
eussNL	some people are having trouble with ps3load/ps3loadx with launching it fselfs on CFWs
eussNL	and with makeself for the same reason I suppose
irssi_	devs won't support it if the CFW doesn't run it
Mathieulh	if the cfw doesn't run fself, it's not complete
Mathieulh	at least not to me
Mathieulh	all my personal cfw all run fself natively
eussNL	hmmm, seems a thing to add to MFW then... appldr patch for fselfs - if it isnt working now



the 4 byte patch he speaks of is:
< 00001360 40 80 0e 0c 20 00 57 83 32 00 04 80 32 80 80 8e |@... .W.2...2...|

Conclusion / Status

Although it is possible to add as a task, it is not recommended in general. There is brick risk. 

  <mall0ry> eussNL, that appldr fself patch is risky because it is patching a branch target
